Cisco showcases its 100 gigabit technology at SC11, the international conference for high performance computing, networking, storage, and analysis with the National Oceanic and Atmospheric Administration and National Lambda Rail.

Check out the press release here.

I’m sure most everyone has heard already, but the K supercomputer has been upgraded and now reaches over 10 petaflops.  Wow!

10.51 petaflops, actually, so if you round up, you can say that they “turned it up to 11.”  Ahem.

We’ll actually have Shinji Sumimoto from the K team speaking during the Open MPI BOF at SC’11.  Rolf vandeVaart from NVIDIA will also be discussing their role in Open MPI during the BOF.

We have the 12:15-1:15pm timeslot on Wednesday (room TCC 303); come join us to hear about the present status and future plans for Open MPI.

SC’10 has now ended; in addition to being quite the cardio / leg workout from all the walking, it was a great show.  My December calendar is stacked full of meetings setup as a direct result of discussions from SC’10.  w00t.

Brock and I did our annual post-SC wrapup podcast (ok, it’s only the 2nd time we’ve done it, but it’s an “emerging tradition”).  It’s the one time a year where Brock and I are physically in the same location to do the podcast.

I’ll be on the US Thanksgiving holiday for the next week, so it’s highly unlikely that I’ll add anything here until next week sometime.  Happy Thanksgiving, everyone!

I’m sitting in an airport on a layover while enroute to the Big Easy for #SC10 (i.e., the SuperComputing trade show, for those of you not in the know).  Love the free wifi, Charlotte airport — thanks!

Today’s post is a quickie / roundup of things right before the maelstrom of Supercomputing starts in force tomorrow night… Read More »

Lotsa news coming out in the ramp-up to SC.  Probably the biggest is that about China being the proud owners of the 2.5-petaflop computing monster named “Tianhe-1A”.

Congratulations to all involved!  2.5 petaflops is an enormous achievement.

Just to put this in perspective, there are only three other (publicly disclosed) machines in the world right now that have reached a petaflop: the Oak Ridge US Department of Energy (DoE) “Jaguar” machine hit 1.7 petaflops, China’s “Nebulae” hit 1.3 petaflops, and the Los Alamos US DoE “Roadrunner” machine hit 1.0 petaflops.

While petaflop-and-beyond may stay firmly in the bleeding-edge research domain for quite some time, I’m sure we’ll see more machines of this class over the next few years.   Read More »
